It will be a rare filler with magnetic properties. Magnetite is used for high-density purposes, but it also has characteristics such as thermal conductivity, electrical conductivity, and magnetism.

The MagniF series magnetite is an environmentally friendly material as it is a naturally occurring mineral. With a specific gravity of 5.2g/cc, this high-density filler can increase the density of plastic composites, allowing for weight gain even in small volumes. It is particularly used in the automotive industry for components that require sound and vibration damping effects. Since our products are natural, we can offer them at a lower price compared to synthetic alternatives. Customers looking for magnetic fillers are encouraged to consider our offerings. Feel free to download for more detailed information.
